質して特性に悪影響を及ぼすという問題があった。When starting the battery (1), the cooling medium is heated with a heat exchanger (3) or a heater as shown in Figure 4 when the temperature is raised from the insulated temperature to approximately 120-160°C, which can be raised by the heat of battery reaction. The temperature is increased by circulating and supplying the battery as a heating medium. However, at the start of startup, the temperature of the medium in the circulation path is room temperature, and even if it is heated by a heat exchanger or heater, heat is absorbed in the circulation pipe. low. Therefore, conversely, battery heat is taken away by the medium, causing the battery temperature to drop below the insulating temperature, which causes a problem in that the phosphoric acid electrolyte in the matrix changes in quality and adversely affects the characteristics.

The heating medium is provided with a switching valve controlled so that the heating medium is circulated through the bypass passage without passing through the battery until the heating medium reaches a higher temperature.

作動温度（約１９０℃）に保つ。The battery (1) is composed of a large number of stacked cells, and the separate cooling method shown in Figure 1 has a circulation path (2) for the cooling medium (for example, air) independent of the reaction gas, and the reaction during battery operation is controlled by the separate cooling system. The exhaust medium, which has become high temperature due to the removal of heat, is cooled by a heat exchanger (3) and sent to the battery again by a blower (4) to maintain the battery at a specified operating temperature (approximately 190° C.).

~130℃), but in this case the heat exchanger (3)
Instead of water, steam is passed through the cell, and the cooling medium is used as a heating medium to be circulated and supplied to the battery (1). However, even if the heating medium is heated by the heating initial heat exchanger (3), the temperature of the heating medium supplied to the battery is lower than the battery temperature.

により昇温が行われる。In the initial stage of temperature rise, the battery population valve (7) and outlet valve (7f) are closed, and the bypass valve (8) is open, so the heating medium circulates through the bypass pipe (6) without passing through the battery, causing heating. When the medium temperature≧battery temperature is reached, the output signal from the controller u11 opens the valve +7 (71) and closes the bypass valve (8). Warmth is done.

荷へ給電を開始し、運転状態に入る。When the battery temperature reaches 120 to 130°C, each reaction gas is supplied to the battery, and the load (dummy) temperature is increased using the battery reaction heat. When the battery temperature reaches the specified operating temperature, it starts supplying power to the regular load and enters the operating state.

反応熱を奪って電池を冷却する。The embodiment shown in Figure 2 uses air, which serves as both a cooling gas and a reaction gas, as the cooling medium. During battery operation, the cooling medium (air) is divided into the cooling passage of the battery and the air electrode, and is supplied to the air electrode. The air is used for a cell reaction with the fuel gas supplied to the fuel electrode, and at the same time most of the air flowing through the cooling passage cools the cell by removing reaction heat.

空気温度を下げて電池を冷却する。At this time, the exhaust air from the battery (1) is distributed by the damper (121) into an external exhaust flow and a circulating flow, and this circulating flow is processed by the blower (4) together with fresh air introduced from the outside in proportion to the external exhaust flow. The fresh air is sent to the battery (1).This fresh air compensates for the drop in oxygen partial pressure in the air, and lowers the temperature of the air supplied to the battery to cool the battery.
